Astromancy

A fire so bright. It speaks the tongue of the infinite, holds hands with neighboring stars.

In the night sky, constellations look down at the world and ask themselves what it is like to live there. They tell stories of travelers from beyond and make wishes when one of them falls out of the sky. Some, taken by curiosity, set out to explore.

Astromancy is an Arcana based on the use of Astral Stones, strange gems found all across Aedrelon reacting to the light of the many celestial bodies seen in the skies. These stones can be linked to single stars, to constellations, to a moon or even to a weather phenomenon for example. By using these stones, an Artist can call forth different miracles linked to its star.
The study of Astromancy is very wide-spread across all of Krogiath, and is one of the most popular course in the Kiln of Aconit, Meilthaor's biggest and most prestigious college of Art. There, students work on a plethora of subjects related to the sky such as astronomy, astrology or meteorology on top of their lessons on the actual usage of Astromancy. Most places of study of this Arcana work in tandem with the local chapter of the Mapmakers to help uncover new Astral Stones and study their properties.
Once an Astromancer is in possession of one such Astral Stone, they may use the powers within. This can only be done if the stone is charged with light. As the stone is left untouched under its specific star, it will slowly absord light until it is full. The light capacity of any given stone is entirely depending on its size. The other condition to use the powers within an Astral Stone is that the corresponding star must be visible in the sky. This makes Astromancy virtually impossible to use inside, during cloudiy nights or during most days. Also, skilled Astromancer may consume less of said light as they develop their knowledge of the stone and its powers. After a couple usage, the stone will be empy and need to be recharged one again. To bypass this issue, it is not uncommon for Astromancers to carry multiples of a same stone or to have a large variety of stones to use.
The powers stored within any Astral Stone are as follows :

• Adjudication : the base power within a stone, it allows an Astromancer to call forth a simple miracle that is depending on the stone used. It uses very little light and can usually be used multiple tiumes before the stone needs to recharge.
• Calling : the Astromancer can use a small part of the light stored in the stone to create an image of the star. This illusion doesn't produce a strong enough light to charge the stone itself, but it is enough to awaken the stone's other powers of the star is not present in the sky or is unseen for any reason.
• Incarnation : the Astromancer becomes an avatar of the star and receives a new appearance as well as new powers. It is a very powerful feat that consumes the entirety of the light stored in the stone. This transformation lasts for a couple minutes and varies wildly depending on the stone used.
• Conjuration : an Exqire of the star appears for a brief moment to aid the Astromancer. The creature obeys the Artists commands and disappears after five minutes. As with the incarnation, this powers consumes all of the light inside the stone and requires a good knowledge of the Arcana to be pulled off consistently.
